HEC yo kwisiga no Kwitaho wenyine

Hydroxyethyl selile HEC ni ikintu cyingenzi mu kwisiga no kwita ku muntu ku giti cye. Ibishobora gukomera hamwe nubwiza bwa hydroxyethyl selulose HEC Gira uruhare rwuzuye mugukomeza kuringaniza, kugirango imiterere yumwimerere yo kwisiga irashobora kugumaho no mubihe bishyushye nubukonje. Mubyongeyeho, ifite imiterere yubushuhe kandi irasanzwe muburyo bwo kwisiga. Cyane cyane mask yo mumaso, toner nibindi byongeweho.

Amavuta yo kwisiga, nkubwoko bwimiti itaziguye kuruhu, abayikoresha bitondera byumwihariko imiterere numutekano wibigize birimo hiyongereyeho ubwiza nibikorwa byo kwita kuruhu.

Nikiis hydroxyethyl selileHEC?

HECHydroxyethyl selulose ni umuhondo wera cyangwa wijimye, utaryoshye, ifu idafite uburozi cyangwa fibrous ikomeye. Muri synthesis na laboratoire, selile yibanze na okiside ya Ethylene (cyangwa chloroethanol) muri rusange ikomatanyirizwa na etherification reaction.

Ibyiza n'imikorere yaHEC:

HEC ifite ibyiza byo kongera ubukonje, uburyo bumwe, igisubizo cya emulisitiya, guhuza, kimwe no kugabanya ihindagurika ry’amazi no gutanga colloide ikingira.

Uruhare ya HEC kwisiga

kwisiga bikubiye mubwoko bwose bwibikomoka kungufu cyangwa inganda zikora inganda zinganda, hamwe nibintu bya fiziki na chimique hagati yabafatanyabikorwa, mugikorwa cyo kwisiga cyakozwe gikeneye kongeramoHEC as emulifier, ibifata birashobora gutuma ubwoko bwibintu bigera kuri plastike ihoraho. Mugukoresha, kwisiga birashobora kandi guhuza nubwoko butandukanye bwuruhu nubushyuhe nubushuhe mubidukikije. Kugirango twongere isoko ryimihindagurikire yisoko ningaruka zo gukoresha abaguzi. Ibikoresho byo kuyoboraHEChydroxyethyl selulose nayo igira uruhare runini mugukomeza uruhu.

Water-soluble polymer compound ikoreshwa mumavuta yo kwisiga

Hariho ibyiciro bisanzwe na sintetike. Amazi asanzwe ya elegitoronike ya polymer ni: ibinyamisogwe, amase y’ibimera, gelatine y’inyamaswa, nibindi, ariko ubuziranenge ntibuhungabana, bwibasirwa n’ikirere, ibidukikije by’imiterere, umusaruro muke, kandi ushobora kwibasirwa na bagiteri, ingaruka hamwe na metamorphic.HECHydroxyethyl selulose synthesis ya polymer-soluble polymer polymer: inzoga za polyvinyl, poly (Ethylene) Pyrrolidone, itajegajega, irakara cyane kuruhu, igiciro gito, bityo aho kugirango amazi asanzwe ya elegitoronike ya polymer ahinduka isoko nyamukuru yibikoresho fatizo bya colloid. Igabanijwemo igice cya sintetike na sintetike yamazi-soluble polymer. Semi-synthique yamazi-soluble polymer yibikoresho bikoreshwa kenshi: methyl selulose, Ethyl selulose, fibre carboxymethyl,Sodium ya Vitamine,HEChydroxyethyl selile, guar gum n'ibiyikomokaho. Synthesis yimyunyu ngugu ya polymer ikunze gukoreshwa: inzoga za polyvinyl, polyvinylpyrrolidone, polymer acrylic. Ibi bikoreshwa mubintu byo kwisiga nkibifatika, kubyimbye, abakora firime, emulizing stabilisateur.
